10× optical zoom
The buttons on the case drive the zoom, the video mode and the selfie: a touchscreen stops responding underwater, buttons do not.

Your phone becomes an underwater camera: waterproof to 10 metres, 10× optical zoom, colour correction, eight hours of battery. Without buying a camera.
The buttons on the case drive the zoom, the video mode and the selfie: a touchscreen stops responding underwater, buttons do not.
A few metres down, red disappears and everything turns blue. Automatic correction gives photos their original colours back.
Up to 165 × 79 × 10 mm: iPhone, Galaxy, Xiaomi, Huawei. No need to change your phone.
A plant-based resin developed by Mitsubishi Chemical: clear, resistant to UV, impact and scratches — and antibacterial.
Photos and video are pulled off and shared from the app, with no cable.
Straight onto the Mix Pro thanks to its built-in float, or onto the Navbow and Navbow+ with the smartphone mount: filming no longer takes your hands.
Freediving, in the pool, or simply feet in the water.

The H1+ adds a depth sensor and a temperature sensor, shown live and able to be overlaid on photos and video, plus time-lapse, an advanced mode and image preview. It weighs 348 g against 375. Everything else — sealing, optics, battery life — is identical.
If it is no larger than 165 × 79 × 10 mm, yes. That covers the large majority of models, iPhone, Samsung Galaxy, Xiaomi and Huawei included.
Ten metres. It is made for swimming, snorkelling and shallow freediving, not for scuba.
Because water absorbs red first. The case's automatic correction restores the original colours, with no editing.
No touchscreen responds underwater — which is why the case has physical buttons: zoom, photo, video, selfie.
The Sublue H1 waterproof case turns a smartphone into an underwater camera: waterproof to 10 metres, 10× optical zoom, 4K video, automatic colour correction and eight hours of battery.
It takes phones up to 165 × 79 × 10 mm and mounts on Sublue underwater scooters — straight onto the Mix Pro, with the smartphone mount on the Navbow.
The phone you already own, in a case that knows how to dive.
